Underbody Coating
UNDERBODY COATING.
Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted. Underbody coating provides long-term protection from corrosion to the car's underbody.
TYPES OF UNDERBODY COATING.
- Rubberized Undercoating
- Polyurethane UndercoatinG.
- Wax or Paraffin-Based Undercoatings
- Asphalt-Based Undercoating
Rubberized Undercoating
Rubberized Undercoating is an easy-to-use black rubberized protective coating. It provides corrosion protection from water, salt, and other chemicals. It helps deaden sound and provides a barrier against rust on cars, trucks, trailers, and other recreational vehicles.
Polyurethane Undercoating.
This type of sealant works by seeping into all cracks and seams, displacing salt and moisture, and oozing around rusty areas to bond with and protect the unoxidized metal. It also sands quickly in case you'll need to perform bodywork and can be painted over.
Wax or Paraffin-Based Undercoatings
Water-based undercoatings are thin-set and have quick drying times. This type of coating can be done by automotive shops that offer undercoating services inexpensively. The downside to water-based undercoatings is the frequency in which they need to be repeated. Often the smallest abrasion that breaks through the undercoating can result in the need for a new coat.
Paraffin-based undercoatings have a wax inclusion that makes them stronger than water-based undercoatings. This type of coating is also a thin-set and relatively fast drying.
Asphalt-Based Undercoating
Asphalt-based undercoating is the strongest undercoating available. It is used on all-terrain and military vehicles. Asphalt-based undercoating will last the longest and is the best option for vehicles that endure heavy road use. Asphalt-based undercoating is the thickest coating with the most damage-resistant properties.
Advantages of underbody coating.
- It extends the lifespan of your car
- No more loud road noise
Disadvantages of Underbody coating.
- It is expensive. Add more to the vehicle maintenance.
